This application is .a continuation.inpartl n of myapplication' filedMay 3. 1924,.,Ser1al No. 7431,120, allowed'Aug. `7', 1926.y l p f' It isa well known fact .that .if water, vapor or'steam isintroduced into.thecylindersior combustion chambers of-an'internal combustion `enginethat' carbonizing y will: be r'educedzY toa-minimum' and that-the.addition steam and vwater vapor to an -explosivemix-p 10. tureplaces vitin'` betterscondition `for combustion inthe engine." Itf-is also a veliknown fact that the introductiouiof.air is beneficial and' increases thegvolume f zfuel, While oil vapor provides better lubricationandrontributes towards better combustion, especially Vwhen certain fuelsare. used. The primary object of my Ainventiozfi `to introduce steam,air, water .and o'l into the fuel Vsupply system of an Ainternalcombuation-engine and this may he accomplished by al1-attachment to thecarbureting devce of the engine or to the intake manifold con-` nectionthereof.

Anotherobjectof my invention is to 'uti- 25 lize the exhaust of aninternal combustion enginefor heating the fuel lsupply to said engine,so asto place the fuel in better condil Vtion forcombustion purposes. Y

The abovev and other objects are attained l by a mechanical constructionthat will be Y hereinafter specifically described. and then claimed, andreference will now Vbe `had 'to' the drawings whereinv 1 Figure 1 is aside elevation of an internal combustion engine equipped with my'attachyfment; i l '1 Figg2 is a vertical sectional view of the manifoldconnection; Y I

Fig.l 3 is -alongitudinal sectional View of an attachment to the airintake of a carburetor, and

Fig. 4 is av cross sectional Aview of the same. Considering Figs. 1 Aand2, I show an internal combustion enginev 1 having a crank case 2,vr anexhaust `manifold 3,`an intake manifold a, a carburetor 5, a throttle 6and. a pedal and bell crank arrangement 7 con-v nected to the throttleand'A operatablefat a footboard 8 arranged below a dash 9, both of whichmay form part of an automobile (not shown).

Interposed between the carburetor 5 and the intakemanifold 4 is thelower angular endlO of a vertically disposed jacketll, said jacketextending'upwardly at the outer side This water reservoir issurroundedving chamber. Ik n A pipe' 33 connects the crank case 2 to the l V.1326. .l semi 4119.108,814. l

Vwhichis 'conducted from the top of the waterV tank 22'by a pipe 28 tothe'mixing chamber 17. An ordinary shut-olfvalve 29may control thesupply of steam throu 28 to themixing chamber 17. A1 The bottom of thereservoir'22 is-connected by a pipe 30 to the mixing chamber 17` andthis pipe is equipped with a valve 31 gh the Pipe i having an operatingrod 32 extendingto the,

connectedto the mixing chamber. 17 so that a desired quantity of air mayenter the mix# ing chamber and it is in this chamber that air, steam,water and oil vapor may be heatn ed'and commingled withthe usuall supplyof fuel from the'carburetor 5.

f' `Instead of supporting the device between the A carburetor andtheintake manifold 4', I may'mountfa somewhat similar device on VVtheairintakev connection 36 ofthe carburetor 5, i'nwhich instance I providethe air v tion 36 ofthe carburetor.
